Let's do a little analysis.... I guess it depends on where the quantity markers (parentheses) are in the minute side of the equation! I submit the clock is a 24 hour clock and it is displaying 18:00 hours (6*3) and then, let's address the potential minutes reading. Are they, (6+7) * 7, or 6 + (7*7)? It must be 6+(7*7) equaling 54, since the (6+7) * 7 equals 91, which is outside the parameters of normal time displays. So, I think the time is 18:54 hours. OR, perhaps the clock manufacturer should have given us a quadratic equation option to program into the minute algorithm.

Now, we have to ask, "Does it really matter?" The answer is, "No." But I can take you back to 1970 when I was young and things were more important:

Oh yes, a Stones fan also! Written by Jerry Ragovoy (Norman Meade) and first recorded by Kai Winding and then Irma Thomas. However, nobody does it better than Mick! I believe the Stones first covered it on their 12 X 5 album.

Thought you might find this interesting. The Shelby factory referenced in this video was two blocks away from where I grew up in Torrance, CA. There were aluminum Cobra bodies on racks on the walls of the factory waiting to be assembled into the epic cars that they became: https://youtu.be/tej4L0Bhpec. It appears that the link to the song may be malfunctioning, so I've included it below:
